Specification of Letters Patent.

Patented Dec. 20 11921.

To all whom, it may concern.

Be it known that I, ANDREW G. Monsoon, a citizen of the United States ofAmerica, residing at Highland Park, in the county of lVayne and State ofMichigan, have invented certain new and useful Improvements inHinge-Gages, of which the following is a specification, reference beinghad therein to the accompanying drawings.

This inventionaelates to devices for 10- cating hinges upon doors, doorcasings and the like, and its object is to provide simple means whichmay be folded into a small space to facilitate its being carried aboutand which is so constructed as to facilitate the accurate location ofthe leaves of a hinge upon a door or other member by providing means foraccurately alining the hinge upon such member.

A further object is to so make such a device that it is particularlyadaptable for locating the leaves of a hinge upon a door and may thenbeapplied to the door casing to accurately locate the correspondingleaves of the hinge upon said casing.

A further object is to provide a device which is universally adjustablefor hinges of different sizes and also for locating hinges upon doorsorother closures of different lengths and to which two or more hingesare to be applied. It is also an object of the invention to provide avery light, simple and compact construction adapted to be carried aspart of the equipment or tools of a carpenter and which is in the natureof a gage or folding rule which may be folded into a small space andcarried in a tool box.

It is alsoan object of the invention to provide certain other new anduseful features in the construction and arrangement of parts.

With the above and other ends in view the invention consists in thematters hereinafter setforth, and more particularly pointed out in theappended claims, reference being had to the accompanying drawing inwhicl Figure 1 is a side elevation of a device embodying the inventionand showing the same as applied to a door casing for use in locatinihinges; thereon;

ig. 2 is an edge elevation of the device;

ig. 3 is a perspective View of the device as applied in'use to the edgeof a door for locating hinges thereon, and

justably held Fig. 4 is a plate.

As illustrating the use of the device embodying the invent-ion, the sameis shown in the drawing as applied to the edge of a door A for locatinghinges thereon and also as applied to a door casing B for locating theother leaves of hinges in proper relation to the hinge leaves on thedoor. It will be understood, however, that the device may be used forlocating hinges accurately upon any hinged closure and upon the casingor other member to which the closure is to be attached by hinges.

The gage or device consists of any desired number of sect-ions or parts1 which are preferably formed of wood of desired size in cross sectionand which parts are preferably of rectangular shape in cross section.These several parts or sections are connected by hinges 2 at theiradjacent ends, said hinges being arranged in alternate relation so thatthe several sect-ions will fold one upon another to form a compactbundle of a length equal to one of the sections so that the gage may beconveniently carried in a tool box.

Certain of the intermediate sections are preferably made in two parts 3and 4, the adjacent ends of which are slidably connected in anysuitablemanner so that they may be adjusted relatively in a longitudinaldirection to lengthen the overall length of the gage and to soadjustably connect these parts the part 3 may be provided with adove-tail groove extending inward from its end and the part 4 providedwith a dove-tail tongue 5 to engage and slide within the groove. Theparts 3 and 4 are held in perspective detail of a scribe their adjustedrelation by any suitable section and into this saw kerf is set asuitable scribe plate 8, preferably formed of thin sheet metal. Each ofthese plates 8 is adwithin its saw kerf or slot 7 by means of pins 9engaging series of transverse openings 19 in the bar and one of a seriesof openings 10 in the plate adjacent the upper and lower edges of theplate. By

removing the pins 9 the plate maybe ad justed-longitudinally of the barand in or out of the slot so that the plate will project a greater orlesser distance from the slot and to facilitate the accurate adjustmentof the plate, guide lines 11 are preferabl provided upon the face orfaces of the p ate to indicate the exact distance at which a 'ver ticalslot 12 formed in the plate parallel with its outer or free edge will befrom the adjacent edge of the bar when the plate is adjusted in its slotto bring one of these lines into coincidence with the edge of the bar.The plate 8 is also formed w1th a slot 13 parallel with one end edge ofthe plate and opening into and extending at right angles to the slot 12.Adjacent the other end of the late a series of parallel slots 14 isformed extending at right angles to and opening into the slot 12. Thedistances between the slot 13 and the several slots 14: represent orcorrespond to' the several lengths of the hinge leaves commonly used Hserting the tool or pencil in the proper slotof the plate and followingthis slot to outline the hinge leaf. After he has so outlined the hingeleaf to be applied to the closure, the gage may be used without furtheradjustment to scribe the corresponding hinge leaf upon the door casingor other part to which the closure is to be attached.

. Secured upon the upper end of the upper section of the gage or bar, issecured a small rectangular plate 15 by meansof a screw 16 passingthrough a slot 17 extending transversely of the plate. This plate is ofgreater width and length than the width and length of the end area ofthe bar to provide an over-hang atone edge of the bar and also at oneside of the bar.

By adjusting this plate transversely upon the end of the bar, the platemay be given an over-hang at either side of the bar.

When the gage is applied to a door A for locating hinges thereon, the"gage is hung upon the door with one edge of the gage or bar in closecontact with the side edge of the door and supported in position by theplate 15 engaging over the upper end of the door. After having adjustedthe scribe plates to correspond with the hinge leaves to be applied, andalso havin adjusted the intermediate bar sections 3 and at to lengthen,

or shorten the overall length of the gage and also adjusting the scribeplates longitudinally of their slots 7 so that the hinges Wlll belocated in their proper relative relation and also in their properplaces upon the door, the carpenter may further secure the gage inposition to accurately hold it while he is scribing the outline of thehinge leaves, by

placing small pins or nails in openings 18 provided therefor in each ofthe scribe plates,

thus detachably tacking these several plates in accurately adjustedposition against the edge of the door. I

After having scribed the outline of the hinge leaves upon the edge ofthe door, the gage is applied as shown in Fig. 1 to the door casing, theplate 15 being placed against the upper horizontal member of the casingwith the edge of the barin close contact Y with the hinge of thevertical side member of the casing and then attaching the several scribeplates to the casing by means of pins in the openin s 18, and thussecurely holding the gage in p ace while he proceedsto scribe theoutline of the corresponding hinge leaves upon the casing.

The'plate 15 is of a thickness to give the proper clearance between theupper'edge of the door and the upper end of the door opening when thedoor is hung, the gage being applied to the casing with the late incontact with the surface of the horlzontal member of the casing, servingto locate the hinge member on the'casing just the thickness of the platefarther down upon the casing than saidhinge members are located from theupper edges of the door.

A very simple device thus provided which may be readily carried about bya carpenter and which may be quickly and easily adjusted by an unskilledperson to properly locate hinges.

Obviously, changes may be made in the construction of the bar and scribeplates and also in the manner in which the severalparts are adjustablyheld, within the scope of the appended claims without departing from thes irit of the invention and I do not there ore limit myself to theconstruction or arrangement shown.

Having thus fully described my invention, what I claim is 1 1. A hingegage including a bar formed of a plurality of hinge connected partsadapted to be folded,'one upon another, and means attached to certain ofsaid parts for locating the osition of hinge leaves upon a for thepurpose is member to w ich the gage is applied, one 'of said parts beingextensible to increase the over-all length of the bar.

2. A hinge gage including a bar to engage an edge of a part to whichhinges are to be applied, a plate adjustably secured to said bar andprojecting laterall therefrom, said plate being provided. wit alongitudinal slot extending parallel with an edge of the bar, and aplurality of slots extending laterally from said slot toward said edgeof the bar, said slot forming guides for marking the outline of hingeleaves.

comprising a plusections adapted plate adjustably the combination of abar rality of hinge connected to fold one on the other, a secured to theend of one of the end sections, and scribing plates of thin sheet metaladjustabl secured to certain of said sections and each formed with alongitudinal slot, and a plurality of-slots extending laterally from thelongitudinal slot.

4. In a device of the character described, the combination of a barcomprising a plurality of hinge connected sections, arrangedlongitudinally of the bar, 3. In a device of the character described, v

end to end to fold one upon the other, and certain of said sectionsbeing formed with longitudinal slots, thin sheet metal plates engaged insaid slots and adjustable therein each of said plates being formed witha slot conforming to the outline of a hinge leaf, a supporting platehaving a transverse slot, and means engaging said slot for holding ablyupon the end of one of the sections of the bar.

In testimony whereof I afiix my signature in the presence of twowitnesses.
